An Abu Dhabi prince captured on videotape torturing a grain merchant has been detained by authorities, CNN reports. Sheik Issa bin Zayed al-Nahyan is under house arrest pending an investigation, officials of the United Arab Emirates have told the US State Department. The videotape shows the prince beating, burning and then using his car to run over his victim. The tape has held up negotiations between the US and UAE on a nuclear pact.
